BOAT-DETACHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 338,164, dated March16, 1886.

Application filed September-15,1885. Serial No.177,192. (No model.)

.To all whom it may concern.-

Be it known that we, Lnwrs L. OREAMER and FRANK A. SPARKS, bothresidents of Millville, in the county of Cumberland and State of NewJersey, have invented certain new and useful Improvements inBoat-Detaching Devices; and we'do herebydeclare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure l is a perspective viewof our improved boat -detaching device, showing the same locked andconnected with the davit-fall. Fig. 2 is a perspective view of ourimproved boat-detaching device, showing the same open and disconnectedfrom the davit-fall. Fig. 3 is a longitudinal vertical sectional viewshowing the device connected with the davit-fall, and with dotted linesshowing the position of the parts in the act of being disconnected whenthe boat touches the water. Fig. 4 is a vertical transverse sectionalview taken on the line w x in Fig. 3. Fig. 5 is an end view, and Fig. 6is a view showing a boat connected with the davit-falls by our improveddetaching device and in position for being lowered.

The same letters refer to the same parts in all the figures.

This invention relates to apparatus for detaching boats from thedavit-falls of vessels,

' whereby they are suspended or supported when not in use; and it hasfor its object to provide a device of this class which shall possesssuperior advantages in point of simplicity, durability, and generalefficiency, and which shall insure the detachment of the boat withabsolute certainty at the moment it touches the water and begins tofloat.

With these ends in view the invention consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described, and particularly pointed out in theclaims.

In the drawings hereto annexed, A designates the base or frame of ourimproved detaching device, which consists, mainly, of the checks or sidepieces, B B, and which is provided at the ends with lugs C 0, havingperforations D, to receive the bolts E, whereby the device may besecured to the boat, one being arranged at the bow and one at the stern,substantially as will be seen in Fig. 6 of the drawings.

The side pieces or checks, B B, are connected by transverse bolts F andG, on the former of which is pivoted a hook or bell'crank lever, H,while on the latter is pivoted a latch-arm, I, provided at its upperend, on the side facing the hook H, with a recess, J, adapted to receiveand hold or retain the upturned pointor nose K of the said hook, whichfits in the upwardly-beveled or indented upper side, L, of the saidrecess J. The upper end of the latcharm I is provided with alaterally-extending arm, M, the object of which will be hereinafter morefully stated.

The cheeks or side pieces, B B, of the device are provided in rear ofthe pivoted latcharm I with bearings for a transversely-sliding pin orbolt, N, which is provided between the said cheeks with a fixed annularring or collar, 0, which serves to limit the sliding motion of the pinor bolt N and to prevent its withdrawal from its bearings. The bottom ofthe frame A has a transverse groove or recess, P, in which is seated anupwardly-bulging spring, Q, which bears against the under side of thering or collar 0, and serves by contact therewith to retain the pin orbolt N securely in any position to which it may be adjusted.

Upon the rear side of the latch-arm I, adjoining one of the side piecesof the frame, and extending over less than one-half the width of thesaid latch-arm, is formed'a heel or shoulder, It, which,when the saidlatch-arm is in a raised position, may rest upon the col lar 0 of pin N,thereby supporting the said latch-arm in its raised position. IVhen thepin N is withdrawn, so as to withdraw the collar 0 from the shoulder R,the weight of the lateral extension or arm M of the latcharm I willcause the latter to tilt over to the vided with perforations S, to whichare secured the ends of a line, T, extending longitudinally throughoutthe length of the boat, and by pulling which at any intermediate pointboth of the said trip-pins may be simultaneously of the drawings, may bereadily connected with the same by simply inserting them between thehooks H and the latch-arms I, striking their lower ends of extensions,and thus bringing their 'upper ends together to the position shown inFig.1 of the drawings. The latch-pins N may now be pushed back under theshoulders R of thelatcharms, thus locking the latter in position andretaining the swivel-links of the davit-falls securely in the detachingdevices. In this position the parts remain while the boat is suspendedfrom the davit-s.

\Vhen the boat is to be lowered,the first thing to be done will be towithdraw thelatchpins N, so as to disengage their collars 0 from theshoulders of the latch-arms. This is accomplished by a single pull uponthe line T, as already set forth. The weight of the boat will serve tohold the inclined point or nose of the hook I-I securely in engagementwith the beveled recess of the latch-arm as long as the davit-falls arekept taut, thus preventing the boat from being detached while it isbeing lowered; but the moment the boat floats in the water and thedavit-falls consequently become slack, the weight of thelaterally-extending arms M of the latch-arms will trip the latter, thusreleasing the hooks H and instantly releasing or detaching the boat fromthe davit-falls.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood without requiring any extended explanation.

The general construction of the device is simple and inexpensive, and itmay be manipulated at anytime with ease and certainty.

The importance is well understood of cansing a boat to become detachedfrom the davit-falls the instant it floats upon the water, especiallywhen the vessel from which it is lowered is under way, or when the seais heavy, as otherwise it would be instantly swamped.

By this invention the trip-bolts, which lock the device securely whenthe boat is not in use, may'be withdrawn before or while the boat isbeing lowered, and the detachment will then take place instantly andautomatically, as well as with absolute certainty, at the be resorted towithout departing from the spirit of our invention.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States 1. In a device for detaching boats,the combination of a frame having checks or side pieces, the hookpivoted between the said side pieces and having an upturned or inclinedpoint or nose, the pivoted latch-arm having a beveled recess adapted toreceive and retain the point of the hook, and provided with a weight orarm, and having a heel or shoulder formed upon its rear side, and thetrip pin or bolt arranged to slide transversely in suitable bearings inthe side pieces of the frame, and having a ring or collar arrangedbetween the said side pieces, all constructed, arranged, and operatingsubstantially as and for the purpose set forth.

2. In a device for detaching boats, the combination of the frame, thehook having an upturned point or nose pivoted between the sides of 'saidframe, the latch-arm having a beveled recess, a laterally-extendingweight or arm, and a heel or shoulder formed on its rear side, thetransversely-sliding trip pin or bolt having a ring or collar adapted toengage the said heel or shoulder, and an upwardly-bulging springarranged in a transverse groove in the base of the frame and adapted tobear against the collar of the tripbolt, and to retain the latter in anyposition to which it may be adj usted, substantially as and for thepurpose herein shown and specified.

3. As an improvement in devices for detaching boats, theherein-described frames secured one at the bow and another at the sternof the boat, each provided with a pivoted hook having an upturned pointor nose, a pivoted latch-arm having a beveled recess adapted to retainthe said point or nose, a laterally-extending weight or arm, and a heelor shoulder, a transversely sliding trip pin or bolt having an annularcollar adapted to bear against the said heel or shoulder, and adetaining-spring arranged to bear against the collar of the trip-pin, incombination with a line extending longitudinally through the boat andconnecting the inner ends of the trip pins or bolts, which may therebybe simultaneously withdrawn from engagement with the heels or shouldersof the latch-arms, and the our own we have hereunto affixed oursignadavit-falls having swiveled links attached to tures in presence oftwo witnesses.
